Yesterday I've tried to import another DUMP as a new Oracle schema and failed to to limited space. So the impdp exited with an error. I've successfully deleted outdated schemas using the sysadmin account and then tried to start the import again. Now it always throws the following error code and I've not yet found a solution (sorry for german output):

The user is sys! That error occurs since the broken import from before... all things have been setup properly. Oracle produces different errors since than. For example I'm also not able to export data using exp or expdp.
